During operation, a plurality of lawn filaments output from the wire drawing machine enter the central hole of the rotating shaft after passing through the guide wheel and the traction roller, meanwhile, the artificial lawn yarns unwind from the yarn cylinder and enter the central hole of the rotating shaft, the artificial lawn yarns rapidly wrap and bind the lawn filaments to form artificial grass filaments capable of being directly tufted through high-speed rotation of the yarn cylinder, and the traction mechanism and the winding mechanism below the rotating shaft sequentially pull and wind the grass filaments for later working procedures.
However, the grass yarn cladding machine with the structure has the following three disadvantages in the actual working process:
(1) When the yarn cylinder is unreeled under the high-speed rotation action of the rotating shaft, the artificial turf yarn on the yarn cylinder is always in a free splashing state due to the action of centrifugal force, and the tension state of the artificial turf yarn cannot be controlled and is in an uncontrolled state, so that the artificial turf yarn is easy to break, and the tension of grass filaments formed after binding and twisting is uneven;
(2) Because the artificial turf yarns on the yarn cylinder are loose and have different tightness, the artificial turf yarns directly enter the central hole of the rotating shaft to wrap the binding turf yarns, so that the tension of the formed grass yarns is uneven;
(3) Because the rotation shaft is in different rotation speed states, the tension of the artificial turf yarn unreeled on the yarn cylinder can be changed, and thus the tension of the formed grass yarns is uneven after the artificial turf yarn enters the central hole of the rotation shaft to wrap the binding grass yarns.
In summary, the grass yarn produced by the existing grass yarn cladding machine is uneven in tension, so that the product quality is greatly reduced, and the length of the grass yarn and the length of the artificial turf yarn in unit length are different due to the grass yarn with uneven tension.
